Why go
This is where bouldering grew up and where the Font grade began. The ONF counts about 30,000 sandstone boulders in the forest south of Paris and some 4 million climbing visits a year. The first painted circuit appeared at Cuvier Rempart in 1947.
The route
Bas Cuvier, between Fontainebleau and Barbizon, is the old heart of Bleau, with circuits from orange (AD+) to white (ED+). La Marie-Rose, a 6a wall on slopers first climbed by René Ferlet, is the problem everyone queues for, and Le Carnage (7b+) is the classic roof. The Gorges d'Apremont, painted from 1952, have classics such as Le Croque-Mitaine (5+) and Le Mur des Lamentations (7a). Franchard Isatis is the third great sector. Circuits follow painted numbers and arrows, and the colour gives the adjectival grade: yellow PD, orange AD, blue D, red TD, black or white ED.
When to go
Friction is best on cold, dry days, so most climbers come between late October and mid-March, with spring and autumn as the milder choice. Warm, humid weather makes the rock greasy.
Getting there
Trains on Ligne R from Paris Gare de Lyon reach Fontainebleau-Avon in about 47 minutes and Bois-le-Roi in about 42. From Fontainebleau-Avon, bus 21 runs to Barbizon Cimetière in about 20 minutes, a 20 to 25 minute walk from Bas Cuvier and 15 minutes from Apremont. Drivers park at the Carrefour de l'Épine for Bas Cuvier.
Permits and booking
No permit or fee is needed. Stay on the marked circuits, and respect ONF bans such as the 2023 climbing closure on the north side of the Restant du Long Rocher, which protects rare mosses. Fire and sleeping in the forest are not allowed. A fire that began on 12 July 2026 burned about 2,000 ha, and 80 percent of the massif reopened on 22 August. As of 1 September most of the Trois Pignons, Cul de Chien and Roche aux Sabots stayed closed, along with parts of Apremont (Envers, Est, Solitude, Sully), while Cuvier, Franchard and the Éléphant were open. Check the ONF map.
How hard it is
Font grades feel stiff, and circuits mix slab, mantel and slopers on rounded, sandy rock. Landings are sand and roots, so bring a pad and a spotter. Never climb wet sandstone: it stays weak inside after the surface dries.
Where to sleep
Fontainebleau town and Bois-le-Roi have hotels and gîtes. Fontainebl'hostel at La Chapelle-la-Reine, 12 km from Fontainebleau, opens all year and is a 35 minute walk from the Éléphant.
Tips
- Wipe your shoes on a rag before every attempt, use little chalk, and brush it off afterwards with a soft brush, never a wire one.
- Lift your pad rather than dragging it, since the ground around popular boulders is eroding.
